Michael Schurter 4d081490e6 Add Cleanup method to Driver interface 
Cleanup can be used for cleaning up resources created by drivers to run
a task. Initially the Docker driver is the only user (to remove
downloaded images).

Alex Dadgar 2be221d664 Don't retrieve Driver Stats if unsupported 
This PR makes us only try to collect stats once if the Driver doesn't
support collecting stats.

Michael Schurter 770ed703d0 Add Driver.Prestart method 
The Driver.Prestart method currently does very little but lays the
foundation for where lifecycle plugins can interleave execution _after_
task environment setup but _before_ the task starts.

Currently Prestart does two things:

* Any driver specific task environment building
* Download Docker images

This change also attaches a TaskEvent emitter to Drivers, so they can
emit events during task initialization.
